Description

The present invention relates to a compartment penetration treatment structure, a compartment penetration treatment member, and a compartment penetration treatment method used for a fireproof structure of a building.

In buildings such as apartment houses, office buildings, and schools, partition penetrations such as walls may be provided with compartment penetrations in order to insert long inserts such as cables and pipes. The section penetration portion is required to have a structure (fire prevention structure) in which fire prevention measures are taken in order to prevent the spread of fire to the other section when a fire breaks out in any section. The partition portion is generally a hollow wall composed of two wall portions and having a hollow portion between the wall portions.

As a method of forming a compartment penetrating portion into a fireproof structure, for example, a method of filling a gap between a long insertion body and a through hole with a fireproof putty is known (see, for example, Patent Document 1).
Further, a method of filling the gap between the insertion body and the through hole with an amorphous filler such as a fireproof pack in which a fireproof putty is packed inside the bag has been proposed (see, for example, Patent Document 2). When using an amorphous filler, it is common to use a refractory pack in which a predetermined amount of refractory putty is packed inside the bag or a product in which a sleeve is made into a kit.
Further, in order to facilitate the installation of the fire-resistant putty and the amorphous filler and improve the fire resistance and the fire extinguishing property, a tubular insertion member may be arranged in the compartment penetrating portion. The insertion member exhibits fire resistance and fire extinguishing performance by being arranged at an appropriate position in the section penetrating portion. The insertion member has an elastic protrusion, and the elastic protrusion protrudes to the outside of the through hole and can be easily installed in the through hole by hanging it on the outside of the through hole (see, for example, Patent Document 3).

Japanese Patent No. 6348320 Japanese Patent No. 6150933 Japanese Patent No. 5779435

However, long insertion bodies such as cables and pipes are passed through the inside of the insertion member, and if the insertion body is moved after the insertion member is installed, the inside of the insertion member and the insertion member is fireproof. It may shift from the proper position where the putty etc. was installed. In addition, due to an external force such as an earthquake, the insertion member or the like may be displaced from the appropriate position where it was installed. In this way, it is difficult to exhibit the fire resistance and fire extinguishing performance desired as the fire protection structure of the compartment penetration part due to the deviation from the appropriate position where the insertion member and the fire resistance putty inside the insertion member were installed. It becomes.

Therefore, in view of the above problems, the present invention has a compartment penetration processing structure in which the members used in the fire protection structure of a building efficiently exhibit fire resistance and fire extinguishing performance, and the insertion members used in the fire protection structure of the building are suppressed from being displaced.

Hereinafter, the present invention will be described in more detail using embodiments.

[First Embodiment]
As shown in FIG. 1, the compartment penetration processing structure according to the first embodiment of the present invention is a compartment penetration portion 15 formed in a partition portion 11 of a building and into which a long insertion body 21 is inserted. It is a compartment penetration processing structure with a fireproof structure.
The compartment penetration processing member used in the compartment penetration processing structure according to the first embodiment of the present invention includes an insertion member 3, a locking member 4, and a covering portion 5.

The partition portion 11 in the compartment penetration processing structure of the present invention is a member that partitions between compartments (first compartment A and second compartment B) on the wall surface of the building, and is from one outer surface 11A side of the partition portion 11. It has a compartment penetrating portion 15 penetrating the other outer surface 11B side. The partition portion 11 shown in FIG. 1 is a hollow wall, and is composed of two wall materials (partition materials) 12A and 12B arranged via an interval (hollow portion 13). Therefore, the section penetrating portion 15 is composed of a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and a hollow portion 13 between them. Then, the outer surface of one wall material 12A constitutes the outer surface 11A of the partition portion 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition portion 11. The through holes 13A and 13B are circular, elliptical, or oval so that the outer peripheral surface of the insertion member 3 can match the shape of the inner peripheral surface of the through holes 13A and 13B when the insertion member 3 described later is inserted. , It suffices to have a shape similar to these. The through holes 13A and 13B on the outer surfaces 11A and 11B respectively constitute openings 13C and 13D of the partition penetrating portion 15 provided in the partition portion 11.

[Insert member]
The insertion member 3 is inserted into the compartment penetrating portion 15 in a sleeve shape, and is arranged in the compartment penetrating portion 15 so that the insertion body 21 is passed through the inside of the sleeve. Here, the sleeve-shaped insertion member 3 is passed from one through hole 13A to the other through hole 13B in the section penetration portion 15. The insertion member 3 can prevent the hollow portion 13 and the outside of the partition portion 11 from communicating with each other.
The insertion member 3 is sleeve-shaped or deformable into a sleeve-like shape. Here, the insertion member 3 that can be deformed into a sleeve shape is a sheet-shaped insertion member 3 that is deformed into a sleeve shape with its ends facing each other and inserted into the compartment penetrating portion 15. To say. The sheet-shaped insertion member 3 is not limited to the sheet-shaped one from the beginning, but also includes a sheet-shaped one that is unwound from the roll. However, when the insertion member 3 is deformed into a sleeve shape, the end portions of the sheet-shaped insertion member 3 are not limited to abutment, and the end portions may overlap each other to form a sleeve shape. .. Since the insertion member 3 is deformable into a sleeve shape, the size of the insertion member 3 can be adjusted according to the size of the through holes 13A and 13B at the construction site to form a sleeve shape. It can accommodate compartment penetrations 15 of various sizes. The thickness of the sheet-shaped or roll-shaped inserting member 3 is not particularly limited, but is, for example, 0.01 to 10 mm, preferably 0.05 to 5 mm. The insertion member 3 is preferably flexible so that it can be deformed into a sleeve shape.

The insertion member 3 is made of a refractory material. The refractory material is preferably a heat-expandable member that expands by heating. The heat-expandable member expands in the event of a fire to prevent the spread of fire.
The heat-expandable member is formed of a heat-expandable resin composition. The heat-expandable resin composition contains a resin component and a heat-expandable material. By forming the insertion member 3 with a heat-expandable resin composition containing a resin component, it becomes easy to form and deform the curved shape of the insertion member 3, and the insertion member 3 can be made into a sleeve shape as described above.
Examples of the heat-expandable material include heat-expandable inorganic substances. By using a heat-expandable inorganic substance, it is appropriately expanded by heating a fire, and the mechanical strength of the expanded residue after expansion is excellent, so that the fire resistance can be easily improved.

By setting these lower limits or less, it is possible to prevent the thermally expandable material from accidentally expanding due to heating other than fire. Further, by setting the value to the upper limit or less, it becomes easy to surely expand the heat-expandable material by heating the fire.
Further, the expansion start temperature of the heat-expandable material is such that a predetermined amount (for example, 100 mg) of the heat-expandable material is heated at a constant temperature rise rate (for example, 10 ° C./min), and a force in the normal direction rises. It can be measured by measuring the temperature. The measuring device may be any device capable of controlling the measurement temperature and measuring the stress in the normal direction, and for example, a rheometer may be used.
The expansion coefficient of the thermally expandable member is preferably 3 times or more, and preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but is, for example, 50 times. The coefficient of thermal expansion was determined by supplying a heat-expandable member to an electric furnace, heating it at 600 ° C. for 30 minutes, and then measuring the thickness of the test piece (thickness of the test piece after heating) / (before heating). It is better to calculate by the thickness of the test piece).
